Abstract: PURPOSE:To increase a contact surface pressure by cutting a lower side surface internal periphery to tilt a lap surface against a cylinder internal peripheral surface the case of forming the lap surface by lapping work to the peripheral surface of a piston ring. CONSTITUTION:A main unit peripheral surface 14 of a piston ring 11 is given a tapered angle gamma1 by tapering work. After a plating layer is formed on the tapered face-shaped peripheral surface 14, a lower side surface internal peripheral cut 12 is formed, and a plurality of the piston rings are simultaneously lapped, in a condition that a piston ring main unit is twisted, to prepare a lap surface 15. Next, lapping work is performed relating to a width 11 to prepare the lap surface 15. After work of the lap surface 15, an upper side surface internal peripheral cut 16 and/or upper/lower keystone surfaces 13, 17 are worked. In this way, the lap surface 15 shows a tilt of tapered angle gamma2 relating to a perpendicular surface, in a free condition. As a result, at the time of use, the lap surface 15 of the piston ring 11 generates a very high surface pressure by line contact, and improvement of oil scraping performance and shortening of an initial run-in period can be attained.

Filed: 1985-12-13
Abstract: PURPOSE:To prevent a through current from flowing between a sense amplifier and a sense output latch circuit by providing a gate circuit to the input stage of the latch circuit and latching its output in an FF which operates complementarily to the gate circuit. CONSTITUTION:When a clock phi for sense amplifier control goes up to '1', the clocked CMOS inverter 12 of the sense output latch circuit 10 operates to read out the sense output of the sense amplifier 1 in operation. At this time, the clocked CMOS inverter 18 of the FF of the circuit 10 is off, and put in operation when the clock phi goes down to '0' to turn off the inverter 12 and amplifier 1, so that the FF latches the output of the inverter 12. No through current, therefore, flows between the amplifier 1 and inverter 12 which are off in a data holding state to reduce the current consumption; and the input level of the latch circuit is affected by only the sense output of the sense amplifier and the dimension determination of the transistor of the inverter 12 is facilitated, so that designing is facilitated.

A CPU72, after initializing a memory to zero for an L representing the length of the output signal of the line sensor 56 and an S representing the area, reads in the voltage of the output signal in order. And the CPU finds the absolute value of the difference between the output signals of adjacent picture elements, and adds the absolute value on the L, and substitutes an added result for the L, then stores it. The CPU72 finds a complexity degree (e) stipulated in an equation (e)=L2/S by using the L and the S. The CPU72 repeats an operation by moving the projecting lens 20 by a prescribed quantity, and finds the position of the projecting lens 20 where the complexity degree (e) becomes maximum, and sets the position as the focal position. In such a way, it is possible to perform the discrimination for the focusing with high accuracy.

Title: Waveform crack removing device for transmission line
Inventor: UENO TATSUYA
IPC: H04B3/04
Filed: 1997-10-14
Abstract: PROBLEM TO BE SOLVED: To prevent a receiver from malfunctioning by making small a waveform crack of the transmission line due to capacitive reflection that the device generates by canceling the waveform crack by giving extra length to a transmission line end and putting open reflection generated at an open end of the extra length and the capacitive reflection from the device one over the other. SOLUTION: On the transmission line 1, a receiver, a driver, and the device are connected. The extra length 10 is given to the end of the transmission line 1. When the device 1 is driven, a drive wave is propagated to the receiver side and the device 2 and when the drive wave reaches the device 2, the capacitive reflection is caused. The drive wave propagated to the receiver side causes the open reflection at the end of the extra length 10. This open reflection is in phase with the drive wave propagated from the driver and has an amplitude twice as large as the drive wave and the reflection is propagated to the receiver side. The open reflection and the capacitive reflection from the device are put one over the other to cancel the waveform crack.
